Description

Technical Field

[0001] The invention relates to the technical field of autonomous breathing training, and in particular to a portable autonomous breathing training management device for breast radiotherapy. Background Art

[0002] Deep Inspiration Breath Hold (DIBH) is a technique used in radiotherapy, especially in the treatment of breast cancer. This technique significantly reduces the radiation dose to the heart and other important organs during radiotherapy by guiding patients to take a deep breath and hold their breath, thereby reducing the risk of related adverse reactions. In actual treatment, the patient needs to lie flat with his arms above his head. The doctor draws a mark on the side of the patient's chest. The patient concentrates on breathing with his chest, taking a deep breath and holding his breath for more than 35 seconds. When the patient exhales quietly and ends the deep breath hold, the mark needs to be moved up about 1.5 cm, and this breathing pattern is repeated many times during the treatment.

[0003] In the modern living environment, it is difficult to avoid inhaling particles of different concentrations and sizes in the air. Inhaling a large amount of particles may cause varying degrees of damage to the patient's mucociliary clearance system and alveoli, especially for patients undergoing deep inhalation and breath-holding training. The tidal volume during breathing training is several times higher than that of calm breathing. Inhaling a large amount of particles in the air may cause lung infection.

[0004] For example, a Chinese patent with publication number CN104208845A discloses a breathing training device, including an inhalation training component, an exhalation training component, a gas drainage component and a breathing terminal, wherein the inhalation floating component and the exhalation floating component are respectively provided with an inhalation ventilating tube and an exhalation ventilating tube that penetrate the inhalation floating component and the exhalation floating component, and the inhalation ventilating tube and the exhalation ventilating tube are also provided with an inhalation indicating float and an exhalation indicating float inside. The breathing training device not only enables the inhalation training and the exhalation training to be carried out synchronously in a healthy breathing environment, thereby improving the vital capacity, but also has the function of indicating the recovery of the vital capacity. In the above-mentioned breathing training device, the inhaled and exhaled gases need to pass through the slender drainage component, which additionally increases the breathing resistance, and the device has too many components and is inconvenient to operate, so it is inconvenient for the user to wear it for daily training. Therefore, the present invention provides a portable autonomous breathing training management device for breast radiotherapy to meet the needs. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a portable autonomous breathing training management device for breast radiotherapy. By setting an airflow adjustment component, not only can the airflow be quickly adjusted, but the inhaled gas can be filtered according to the size of the airflow, so that the air entering the patient's lungs is cleaner and the safety of the device is improved. Secondly, the airflow adjustment component can be freely disassembled and assembled on the outer shell, and the structure is simple and easy to produce and promote, which conforms to the actual application scenario. The user can adjust the airflow simply and conveniently, and the adjustment freedom is high. The above settings can solve the problem that traditional breathing training devices cannot ensure the safety of air entering the user's body and the user's inconvenience in adjustment during the process.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions: A portable autonomous breathing training management device for breast radiotherapy comprises a shell, both sides of which are fixedly connected with fixing mechanisms, the fixing mechanisms are used to wear the shell on the cheeks of a user, and reinforcing ribs are fixedly connected to the inner wall of the shell; an airflow regulating component, the airflow regulating component is used to adjust the airflow volume of the user's breathing, and the airflow regulating component is connected to the shell.

[0007] Optionally, the airflow adjustment component includes an outer fixing sleeve fixedly connected to the outer wall of the shell, and also includes an inner filter sleeve fixedly connected to the inner wall of the shell, the outer fixing sleeve is plugged with an adjustment sleeve, and one end of the adjustment sleeve is rotatably connected to a plurality of baffles.

[0008] Optionally, an outer sheet body is fixedly connected to the outer circumference of the bottom of the adjustment sleeve, an inner sheet body is fixedly connected to the inner circumference of the bottom of the adjustment sleeve, an insert block is fixedly connected to the bottom of the inner sheet body, and a slot is provided in the outer fixed sleeve.

[0009] Optionally, a protrusion is fixedly connected at the middle position of the outer sheet, a groove matching the contour of the protrusion is provided on the outer wall of the outer fixed sleeve, the end of the outer sheet has an outwardly turned arc, and a segmented groove is provided on the outer sheet.

[0010] Optionally, the insert block has a plurality of outwardly protruding arc-shaped structures, and a multi-stage sealing gasket is fixedly connected in the slot, and the multi-stage sealing gasket is a curved elastic structure.

[0011] Optionally, a support frame is fixedly connected to the inner wall of the adjustment sleeve, a limiting sleeve is fixedly connected at the middle position of the support frame, a first diverter plate is fixedly connected to the support frame, a rotating rod is rotatably connected inside the limiting sleeve, one end of the rotating rod is fixedly connected to a handle, and the other end of the rotating rod is fixedly connected to a rubber plug.

[0012] Optionally, a positioning groove is provided on the outer wall of the adjusting sleeve, and a positioning block having a shape matching that of the positioning groove is fixedly connected to the inner wall of the outer fixing sleeve, and one end of the positioning block is a triangular structure.

[0013] Optionally, a guide portion is fixedly connected to the outer circumference of the stop pad, a guide groove matching the contour of the guide portion is opened on the inner wall of the adjustment sleeve, and a first limit block, a second limit block and a third limit block are fixedly connected to both sides of the stop pad.

[0014] Optionally, an inner frame is installed in the baffle, the contour of the inner frame matches the contour of the baffle, and the material of the inner frame is steel wire.

[0015] Optionally, a second diverter plate is fixedly connected inside the inner filter sleeve, a plurality of first filter screens arranged linearly are fixedly connected inside the inner filter sleeve, and a second filter screen is fixedly connected between the inner filter sleeve and the outer shell.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects: In the above scheme, by setting up an airflow adjustment component, not only can the airflow be quickly adjusted, but also the inhaled gas can be filtered according to the size of the airflow, so that the air entering the patient's lungs is cleaner and the safety of the device is improved. Secondly, the airflow adjustment component can be freely disassembled and assembled on the outer shell, and the structure is simple and easy to produce and promote, which conforms to the actual application scenario. The user can adjust the airflow simply and conveniently, and the adjustment freedom is high.

[0017] By arranging an outer sheet body and an inner sheet body in the airflow adjustment component, when the user disassembles the adjustment sleeve, the outer sheet body can be pried outward to make the protrusion disengage from the groove, and then the adjustment sleeve can be pulled outward to remove the adjustment sleeve from the outer fixed sleeve. This disassembly and assembly method is simple to operate. The setting of the multi-stage sealing gasket can not only achieve a sealing effect on the adjustment sleeve and the outer fixed sleeve during the process of inserting the plug into the slot, but also has a multi-stage sealing effect with better airtightness.

[0018] By arranging a baffle and a guide part in the airflow adjustment component, a guide groove which is compatible with the position and height of each baffle is opened on the inner wall of the adjustment sleeve, and the guide part is inserted in the guide groove, and the guide groove can limit the guide part. Such an arrangement prevents the baffle from being misplaced or detached during rotation. In addition, the length of the guide groove varies according to the rotation range of each baffle. Such an arrangement is to prevent each baffle from continuing to rotate after rotating to a specified angle, thereby ensuring that there is no misplacement between the baffles. The baffle can only rotate within the range of the corresponding guide groove, thereby improving the accuracy of the device during adjustment.

[0019] An inner skeleton is arranged in the airflow regulating component, and the material of the inner skeleton is steel wire. Such material makes the inner skeleton have a certain strength. Since the material of the baffle is rubber, the inner skeleton of steel wire can improve the structural strength of the baffle, so that the baffle is not easy to deform during rotation, thereby improving the sealing between the baffle and the regulating sleeve. In addition, the manufacturing cost of the steel wire and the baffle is low, and they are easy to produce and assemble.

[0020] By arranging an inner filter sleeve in the airflow regulating component, a second filter is arranged at the connection position between the inner filter sleeve and the outer shell, the second filter can perform preliminary filtration on the inhaled air, and a first filter is also arranged in the inner filter sleeve. The first filter is installed on the second diversion plate to perform secondary filtration on the air. Such an arrangement makes the air entering the user's body cleaner and safer.

[0021] By arranging a first diverter plate and a second diverter plate in the air flow adjustment component, the two sets of diverter plates can block and limit the air, allowing the air to flow in a straight line along the position where the baffle is installed into the adjustment sleeve and the inner filter sleeve. The filtering structure of the inner filter sleeve is set according to the opening size during the expansion of the baffle. Such a setting is based on the different air flow rates under different opening sizes, so the filter effect is different. While minimizing the cost, it does not affect the filtering effect of the filter on the air, thereby improving the practicality of the present application. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] like Figures 1 to 15As shown, an embodiment of the present invention provides a portable autonomous breathing training management device for breast radiotherapy, including a shell 1, both sides of the shell 1 are fixedly connected with a fixing mechanism 101, the fixing mechanism 101 is used to wear the shell 1 on the cheek of the user, and the inner wall of the shell 1 is fixedly connected with a reinforcing rib 102; an airflow adjustment component, the airflow adjustment component is used to adjust the airflow volume of the user's breathing, and the airflow adjustment component is connected to the shell 1. When the user needs to wear the breathing training management device provided by the present application on the cheek, the fixing mechanism 101 is required. The fixing mechanism 101 is an elastic ear-hook strap. The user hangs the fixing mechanism 101 behind the auricle to achieve the wearing effect. Optionally, the ear-hook strap is provided with a metal buckle with adjustable strap length, and the user can adjust the strap length according to the user's preference. The size of the fixing mechanism 101 can be adjusted according to the contour of one's cheek using a metal buckle, thereby making the application range of the breathing training management device wider. When the user wears the shell 1 on the cheek, the shell 1 will fit the contour of the user's face to form an enclosed space. Optionally, a rubber sealing pad is provided at the edge of the shell 1 to improve the sealing effect between the shell 1 and the cheek. At this time, the user can use the airflow adjustment component to adjust the size of the gas flow aperture between the shell 1 and the cheek, and then adjust the size of the airflow flow inside the shell 1 to achieve the function of breathing training. The wearing method of the breathing training management device provided in this application is similar to the wearing method of a mask. Wearing it on the user's face for breathing training can not only free the user's hands, but also provide better feedback during training.

[0032] By setting up an airflow adjustment component, the present application can not only realize rapid adjustment of the airflow rate, but also filter the inhaled gas according to the size of the airflow rate, so that the air entering the patient's lungs is cleaner and the safety of the device is improved. Secondly, the airflow adjustment component can be freely disassembled and assembled on the shell 1, and the structure is simple and easy to produce and promote, which is in line with actual application scenarios. The user can adjust the airflow rate simply and conveniently, and the adjustment freedom is high.

[0033] In this embodiment, if Figures 1 to 9As shown, the airflow adjustment component includes an outer fixed sleeve 2 fixedly connected to the outer wall of the shell 1, and also includes an inner filter sleeve 7 fixedly connected to the inner wall of the shell 1, an adjustment sleeve 3 is plugged into the outer fixed sleeve 2, one end of the adjustment sleeve 3 is rotatably connected to a plurality of baffles 4, an outer sheet body 301 is fixedly connected to the outer circumference of the bottom of the adjustment sleeve 3, an inner sheet body 303 is fixedly connected to the inner circumference of the bottom of the adjustment sleeve 3, an insert block 304 is fixedly connected to the bottom of the inner sheet body 303, a slot 203 is opened in the outer fixed sleeve 2, and the outer A protrusion 302 is fixedly connected at the middle position of the sheet 301, a groove 201 that matches the contour of the protrusion 302 is opened on the outer wall of the outer fixed sleeve 2, the end of the outer sheet 301 has an outwardly turned arc, a segmented groove 306 is opened on the outer sheet 301, and the plug block 304 has a plurality of outwardly protruding arc structures, a multi-stage sealing gasket 204 is fixedly connected in the slot 203, and the multi-stage sealing gasket 204 is a curved elastic structure, a positioning groove 307 is opened on the outer wall of the adjusting sleeve 3, and the outer fixed sleeve 2 A positioning block 202 that matches the shape of the positioning groove 307 is fixedly connected to the inner wall, and one end of the positioning block 202 is a triangular structure. The airflow adjustment component mentioned above can adjust the gas flow inside the shell 1. Specifically, the airflow adjustment component mainly includes an outer fixing sleeve 2, an inner filter sleeve 7, an adjustment sleeve 3 and a baffle 4, wherein the outer fixing sleeve 2 and the inner filter sleeve 7 are respectively fixed on the outer wall and the inner wall of the shell 1. Specifically, both are made of plastic and the fixing method can be gluing. Such an installation method and material setting are not only low-cost but also easy to produce and manufacture, and are more in line with actual application scenarios. At the same time, they are low-cost and can be accepted by consumers, and are easy to promote and use. The adjustment sleeve 3 is plugged and fixed in the outer fixing sleeve 2. The setting of the non-fixed structure makes it easier for the user to disassemble the adjustment sleeve 3 for cleaning and maintenance. The baffle 4 is installed at the end of the adjustment sleeve 3 and can also be disassembled. Because the adjustment sleeve 3 and the baffle 4 are the core adjustment structures, they are both detachable structures considering maintenance and cleaning, and are easy to disassemble and assemble.

[0034] The outer sheet 301 and the inner sheet 303 are respectively installed on the outer circumference and the inner circumference of the bottom of the adjusting sleeve 3. The thickness of the outer sheet 301 is smaller, so it has better flexibility. The outer sheet 301 contacts the outer wall of the outer fixing sleeve 2, and the protrusion 302 of the outer sheet 301 is just snapped into the groove 201. The two can be fixed by the adaptation on the contour to prevent the adjusting sleeve 3 from being separated during use. The arc structure of the end of the outer sheet 301 turned outward and the setting of the segmented groove 306 structure make the end of the outer sheet 301 can be moved. When the user disassembles the adjusting sleeve 3, the outer sheet 301 can be moved outward to make the protrusion separate from the groove 201, and then the adjusting sleeve 3 can be taken out of the outer fixing sleeve 2 by pulling it outward. The thickness of the sheet body 303 is larger than that of the outer sheet body 301. The plug-in block 304 at the end of the inner sheet body 303 is inserted into the slot 203 in the outer fixed sleeve 2. The multiple arc-shaped structures protruding outward on the surface of the plug-in block 304 can cooperate with the structure of the multi-stage sealing gasket 204. Specifically, the multi-stage sealing gasket 204 is a curved hook-shaped structure, which can cooperate with the arc-shaped structure on the surface of the plug-in block 304. In the process of inserting the plug-in block 304 into the slot 203, the multi-stage sealing gasket 204 with a hook structure is squeezed onto the arc-shaped structure on the surface of the plug-in block 304, and in the process of squeezing, the multi-stage sealing gasket 204 is deformed and pressed against the surface of the plug-in block 304. The material of the multi-stage sealing gasket 204 is rubber. The above structural setting can not only achieve a sealing effect for the two during the process of inserting the plug-in block 304 into the slot 203, but also a multi-stage sealing effect with better airtightness.

[0035] Furthermore, during the process of inserting the adjusting sleeve 3 into the external fixing sleeve 2, the positioning groove 307 on the outer wall of the adjusting sleeve 3 will be plugged into the positioning block 202 on the inner wall of the external fixing sleeve 2. The triangular structure at the end of the positioning block 202 allows the adjusting sleeve 3 to be inserted into the positioning groove 307 with the help of its inclined triangular structure, thereby improving the convenience of operation during the insertion of the two. Secondly, when the two are plugged in, the contour between the positioning block 202 and the positioning groove 307 can limit the adjusting sleeve 3, so that the adjusting sleeve 3 cannot rotate. The above structural setting can prevent the adjusting sleeve 3 from rotating with the stop pad 4 when the user turns the stop pad 4.

[0036] In this embodiment, if Figure 4 , Figure 5 , Figure 7 and Figure 8As shown, a support frame 5 is fixedly connected to the inner wall of the adjustment sleeve 3, a limiting sleeve 501 is fixedly connected at the middle position of the support frame 5, a first diverter plate 502 is fixedly connected to the support frame 5, a rotating rod 6 is rotatably connected in the limiting sleeve 501, one end of the rotating rod 6 is fixedly connected to a handle 601, and the other end of the rotating rod 6 is fixedly connected to a rubber plug 602. The limiting sleeve 501 on the support frame 5 mainly functions to limit the rotating rod 6. The rubber plug 602 at one end of the rotating rod 6 is inserted into the through hole at the end of the limiting sleeve 501. The end structure of the rubber plug 602 is a conical structure, and the material of the rubber plug 602 is rubber material. In the process of assembling the rotating rod 6 into the limiting sleeve 501, the user can push the rotating rod 6 to allow the rubber plug 602 to deform and pass through the through hole at the end of the limiting sleeve 501 to form a fixing effect on the rotating rod 6. The setting of the above structure can achieve a limiting effect on the rotating rod 6 to prevent it from escaping from the limiting sleeve 501 during rotation. Secondly, such a limiting method is not only simple in structure, but also efficient and convenient in the process of disassembly and assembly. A first diverter plate 502 is installed on the support frame 5. The first diverter plate 502 can guide the air sucked in from the baffle 4, so that the airflow enters the interior of the shell 1 along the direction of the first diverter plate 502.

[0037] In this embodiment, if Figure 4 , Figure 5 and Figures 10 to 15 As shown, a guide portion 401 is fixedly connected to the outer circumference of the stop pad 4, a guide groove 305 that matches the contour of the guide portion 401 is opened on the inner wall of the adjustment sleeve 3, a first limit block 402, a second limit block 403 and a third limit block 404 are fixedly connected to both sides of the stop pad 4, an inner skeleton 405 is installed in the stop pad 4, the contour of the inner skeleton 405 matches the contour of the stop pad 4, the material of the inner skeleton 405 is steel wire, and the stop pad 4 can be several in actual use. In the present application, the number of the stop pads 4 is three. Optionally, the user can increase or decrease the number of the stop pads 4 according to their own needs. The three arc-shaped stop pads 4 are distributed in a stepped manner on the top of the adjustment sleeve 3, and the shape formed by the three stop pads 4 when fully unfolded is a circular contour. The top of the joint sleeve 3 is an open structure, and the circular-shaped baffle 4 can block its open structure, thereby blocking the only channel for outside air to enter the shell 1 and the air in the shell 1 to flow out to the outside. A first limit block 402, a second limit block 403 and a third limit block 404 are arranged on both sides of the baffle 4. Specifically, the first limit block 402, the second limit block 403 and the third limit block 404 are rubber material structures with mutually adapted contours, and these three limit blocks can cooperate with each other according to the extended states of the three baffles 4. The baffle 4 has two states: expanded and stored. In the first state, the baffle 4 is in an expanded state. After expansion, two adjacent baffles 4 are blocked and limited by the first limit block 402 and the second limit block 403 (such as Fig.10 and Fig.11As shown in the figure, under the limiting effect of the first limiting block 402 and the second limiting block 403, the two adjacent stoppers 4 are clamped and sealed together to cover the end of the adjustment sleeve 3. In this state, if the user reversely rotates the stopper 4 at the top, the stopper 4 will rotate with the rotating rod 6 as the rotating axis until the first limiting block 402 at the bottom of the stopper 4 hits the third limiting block 404 at the top of the stopper 4 at the middle position (as shown in the figure). Fig.12 and Fig.13 As shown in the figure, the baffle pad 4 at the middle position will rotate with the baffle pad 4 at the top under the blocking action of the first limit block 402 and the third limit block 404, and by analogy, all the baffle pads 4 will be stored and folded together under the continuous rotation of the baffle pad 4 at the top. Whenever the baffle pad 4 is rotated and stored at an angle, an opening will be opened at the end of the adjustment sleeve 3, and the outside air can be sucked into the shell 1 through the opening. The more baffle pads 4 are stored, the larger the opening for air circulation is, the less force the user needs to inhale air, and therefore the lower the intensity of breathing training is. In the second state, the baffle pads 4 are in a fully stored state. In this state, all the baffle pads 4 are stacked and stored on the top of the baffle pad 4 at the bottom (as shown in the figure). Fig.12 As shown), at this time, if the user rotates the baffle 4 at the top in a positive direction, the baffle 4 will unfold again. In the second state, the airflow opening of the breathing training management device is the largest, and the force required for the user to inhale air is the smallest.

[0038] It is worth mentioning that among all the baffles 4, only the baffle 4 at the top is connected and fixed to the rotating rod 6, and the other baffles 4 are not fixed to the rotating rod 6, and one side of the baffle 4 at the bottom is in contact with the support frame 5, and the height of the support frame 5 at this position is flush with the thickness of the baffle 4 (such as Figure 4 and Figure 5 As shown in the figure, when the position of the stop pad 4 needs to be adjusted, the user only needs to rotate the handle 601 at the top of the rotating rod 6. During the rotation of the rotating rod 6, the top stop pad 4 will drive the subsequent stop pads 4 to rotate in sequence. When all the stop pads 4 are stored, if the handle 601 is continuously rotated, the bottom stop pad 4 will come into contact with the support frame 5, and the support frame 5 will block the bottom stop pad 4, so that the stop pad 4 cannot continue to rotate. At this time, the rotating rod 6 cannot continue to rotate to remind the user that the opening has been opened to the maximum state.

[0039] Furthermore, a guide portion 401 is installed on the outer circumference of each stop pad 4, and a guide groove 305 that is compatible with the position and height of each stop pad 4 is opened on the inner wall of the adjustment sleeve 3. The guide portion 401 is inserted into the guide groove 305, and the guide groove 305 can limit the guide portion 401. This arrangement prevents the stop pad 4 from being misplaced or detached during rotation. In addition, the length of the guide groove 305 is different according to the different rotation range of each stop pad 4. This arrangement is to prevent each stop pad 4 from continuing to rotate after rotating to a specified angle, thereby ensuring that there is no misplacement between the stop pads 4. The stop pad 4 can only rotate within the range of the corresponding guide groove 305, thereby improving the accuracy of the device during adjustment.

[0040] Furthermore, each baffle plate 4 is provided with an inner skeleton 405 matching its contour, and the material of the inner skeleton 405 is steel wire, such material makes the inner skeleton 405 have a certain strength, and since the material of the baffle plate 4 is rubber, the inner skeleton 405 of steel wire can improve the structural strength of the baffle plate 4, so that the baffle plate 4 is not easy to deform during the rotation process, and the sealing between the baffle plate 4 and the adjustment sleeve 3 is improved, and the manufacturing cost of the steel wire and the baffle plate 4 is low, and it is easy to produce and assemble.

[0041] As an implementation method in this embodiment, Figure 3 , Figure 5 and Figure 8 As shown, the inner filter sleeve 7 is fixedly connected with a second flow divider plate 702, and a plurality of first filter screens 701 arranged linearly are fixedly connected to the inner filter sleeve 7. A second filter screen 703 is fixedly connected between the inner filter sleeve 7 and the outer shell 1. The second filter screen 703 is arranged at the connection position between the inner filter sleeve 7 and the outer shell 1. The second filter screen 703 can perform preliminary filtering on the inhaled air. It is worth noting that the inner filter sleeve 7 is also provided with a first filter screen 701. The first filter screen 701 is installed on the second flow divider plate 702 to perform secondary filtering on the air. As described above, the first flow divider plate 502 Installed on the support frame 5, the first diverter plate 502 extends from the support frame 5 to the surface of the second filter screen 703. The second diverter plate 702 runs through the entire inner filter sleeve 7 and corresponds to the position of the first diverter plate 502. Therefore, the air entering the adjustment sleeve 3 will first pass through the second filter screen 703 in a direct flow under the blocking action of the first diverter plate 502. After passing through the second filter screen 703, it will continue to pass through the inner filter sleeve 7 in a direct flow under the blocking action of the second diverter plate 702. The end of the inner filter sleeve 7 is a breathable structure. Therefore, the air passing through the first filter screen 701 is directly discharged into the outer shell 1 after being filtered.

[0042] Furthermore, the installation position of the first diverter plate 502 corresponds to the distribution position of the baffle 4. Whenever a baffle 4 is rotated and stored, an opening will be opened, and this opening corresponds to the position of the first diverter plate 502. When the baffle 4 located at the top is rotated and stored, the first opening will be opened. At this time, all air enters the adjustment sleeve 3 through this opening and the first diverter plate 502 corresponding to the opening. At this time, the air channel is relatively narrow and the air flow speed is relatively fast. Therefore, the number of first filters 701 at this position in the inner filter sleeve 7 is relatively large, which can thoroughly filter the air with a relatively fast air flow speed to prevent the air speed from being filtered incompletely due to excessive speed. As the number of openings increases, the number of first filters 701 at the relative position in the inner filter sleeve 7 will also decrease (such as Figure 8 As shown), it can be clearly understood from the above description that the filtering structure of the inner filter sleeve 7 is set according to the opening size during the expansion of the baffle 4. Such a setting is based on the different air flow rates under different opening sizes, so the filter effect is different. While minimizing the cost, it does not affect the filtering effect of the filter on the air, thereby improving the practicality of the present application.

[0043] The working principle of the technical solution provided by the present invention is as follows: When in use, the user hangs the fixing mechanism 101 behind the auricle to wear the shell 1. When the user wears the shell 1 on the cheek, the shell 1 will fit the contour of the user's face to form a closed space. A rubber sealing pad is arranged at the edge of the shell 1 to improve the sealing effect between the shell 1 and the cheek. The circular contour baffle 4 can block its open structure, thereby blocking the only channel for the outside air to enter the shell 1 and the air in the shell 1 to flow out to the outside. The baffle 4 has two states: unfolded and stored. In the first state, the baffle 4 is in an unfolded state. After unfolding, the two adjacent baffles are closed. The pads 4 are blocked and limited by the first limit block 402 and the second limit block 403. Under the limiting effect of the first limit block 402 and the second limit block 403, the two adjacent stop pads 4 are clamped and sealed together to cover the end of the adjustment sleeve 3. In this state, if the user reversely rotates the stop pad 4 at the top, the stop pad 4 will rotate with the rotating rod 6 as the rotation axis until the first limit block 402 at the bottom of the stop pad 4 hits the third limit block 404 at the top of the stop pad 4 at the middle position. At this time, the stop pad 4 at the middle position will be blocked by the first limit block 402 and the third limit block 404. The baffle pads 4 rotate together with the top baffle pad 4, and by analogy, all the baffle pads 4 are stored and folded together under the baffle pad 4 at the top by continuous rotation. Every time the baffle pad 4 is rotated and stored by a certain angle, an opening is opened at the end of the adjustment sleeve 3, and the outside air can be sucked into the shell 1 through the opening. The more baffle pads 4 are stored, the larger the opening for air circulation is, the less force the user needs to inhale air, and therefore the intensity of breathing training is reduced. In the second state, the baffle pads 4 are in a completely stored state. In this state, all the baffle pads 4 are stacked and stored on the top of the baffle pad 4 at the bottom. At this time, if the user rotates forward The baffle pad 4 is turned to the top and will unfold again. In the second state, the airflow opening of the breathing training management device is the largest and the force required for the user to inhale air is the smallest. Therefore, the user can rotate and change the position of the baffle pad 4 according to training needs, thereby changing the size of the air circulation opening to achieve the training effect. The second filter 703 can perform preliminary filtering on the inhaled air. It is worth noting that the first filter 701 is also provided in the inner filter sleeve 7. The first filter 701 is installed on the second diverter plate 702 to perform secondary filtering on the air, thereby ensuring that the air is cleaner and safer when entering the user's body.
